Nope. This is not a cybernetic chipmunk (although wouldn't that be cool). It is a chipmunk with a computerised backpack that is effectively tracking its every move on a tiny processor powered by a wafer thin battery. Now, that may not sound like technology worth investing in to you and me but to ecologists who have to spend thousands of hours in the wilderness tracking small animals, it is a godsend. Moreover, this little gadget was built by one of the most interdisciplinary research teams that I have seen in a long time. Read my full article covering this research in The Economist here.
